Many universities allow a small number of credits attempted or credits completed before they reclassify an applicant from the freshman to the transfer pool.
HOWEVER, hiding any prior college record during the application process is a big deal even if it did not impact the freshman/transfer classification. As katliamom said, consequences may include losing scholarship money, having the offer of admission revoked (even after several semesters of attendance), and possibly losing her visa status. The latter is a big deal because the accrual of “unlawful presence” days can trigger ineligibilities for future US visas.
